Ann Biderman
With more than 2 million viewers tuning into its Sept. 22 finale, Ray Donovan secured its place on the mantel as Showtime’s most successful freshman series, besting the first season of Homeland by more than 30 percent. For her saga about a morally challenged Boston family living in Los Angeles, Biderman (Southland) amassed one of the most impressive casts in years, with movie stars Jon Voight and Liev Schreiber as estranged father and son. Their magnetic performances make them — and the series — instant Emmy contenders.
